Ho ea ka boemo ba ho theha thepa ea coextrusion

Ho ea ka boemo ba ho theha thepa ea coextrusion, mokhoa oa extrusion oa profil ea polasetiki o ka aroloa ka preextrusion le post coextrusion.Pre coextrusion e bua ka motsoako o entsoeng ka lisebelisoa tse peli nakong ea ho etsoa ho sa phethoeng;Post coextrusion e bolela hore thepa e le 'ngoe e thehoa ka ho feletseng ebe e kopantsoe le boitsebiso bo bong.Molemo oa post coextrusion ke hore litšila li ka sebelisoa 'me moruo o molemo.

Ka thepa ea extrusion

Ts'ebetso ea extrusion ea profil ea polasetiki e ka aroloa ka organic co extrusion le inorganic co extrusion ho latela lisebelisoa tse fapaneng tsa extrusion.Organic coextrusion e kenyelletsa pele ho coextrusion ea thepa e ts'oanang (e kang lisebelisoa tse ntle le lisebelisoa tse tsosolositsoeng), preextrusion ea thepa e sa tšoaneng (e kang PMMA le PVC) le post coextrusion ea PVC e bonolo le e thata;Inorganic coextrusion e ka aroloa ka aluminium-plastic composite coextrusion le tšepe ea polasetiki e kopantsoeng ea coextrusion.

Pampiri ena e tsepamisitse maikutlo ho coextrusion ea poso, coextrusion ea polasetiki ea aluminium e entsoeng ka polasetiki, tšepe ea tšepe e kopantsoeng ea profil coextrusion le coextrusion ea mebala e 'meli.

Ha ho bapisoa le thekenoloji ea setso ea FCE, thekenoloji ea post coextrusion e na le melemo ea ts'ebetso e bonolo, ts'ebeliso e bonolo, sekhahla se tlaase sa maqheku, ho hlaphoheloa habonolo le matla a ho khomarela a laolehang.Hajoale, theknoloji e sebelisoa haholo ha ho etsoa profil e nang le mohala oa tiiso bakeng sa mamati le lifensetere.

Theknoloji ea setso ea extrusion ea profil ea polasetiki ea coextrusion ke mohato o le mong oa theknoloji.Thepa e qhibilihisitsoeng e nang le mekhoa e fapaneng ea rheological kapa mebala e fetisoa ho tloha ho li-extruder tse fetang tse peli ho ea ho lefu le tšoanang la ho etsa.Tsena melts phallang ka dikanale tse fapa-fapaneng ka ho theha shoa, 'me joale converge ka shoa bakeng sa extrusion,' me joale vacuum ka setting sleeve ho pholile le seta.
